The U.S. Centers for Disease Control and Prevention (CDC) has confirmed that Covid may be on the rise in some areas of the country, since elevated rates of viral particles have been detected in wastewater samples.

According to the CDC tracker, during the period between February 26, 2022 and March 12, 2022, of the 398 current wastewater sampling sites with active data, 62 sites detected a 100-percent to 999-percent increase in SARS-CoV-2 RNA wastewater levels. Forty-four sites experienced a 1,000-percent increase.

However, some areas saw a decrease in viral RNA detected in wastewater. Twenty-nine sites reported a 100-percent drop, and 48 saw a 10-percent to 99-percent decrease. Some of these sites neighbor those that saw a dramatic uptick; so far, the CDC has not provided any explanation for this.
